19871 divided by 77 
We want to divide 19871 by 77.

Moving on to step 1:
1 divided by 77 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 77

Going ahead to step 2:
19 divided by 77 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 77

On to step 3:
The number 77 fits into 198 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 154 from 198 leaves us with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 77

Moving on to step 4:
77 can be fit into 447 5 times, resulting in a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 385 from 447, we get 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 77

Let's proceed to step 5:
If we divide 621 by 77, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
If we take 616 away from 621, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 6:
77 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 258.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
If we divide 500 by 77, we get 6 and a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 258.06
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
If we divide 380 by 77, we get 4 and a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 258.064
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
77 goes into 720 9 times with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 258.0649
The remainder is 27 after subtracting 693 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
If we divide 270 by 77, we get 3 and a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 258.06493
If we subtract 231 from 270, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
If we divide 390 by 77, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 258.064935
Subtract 385 from 390 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
77 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 258.064935
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
500 divided by 77 is 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 258.06493506
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 258.06493506 with a remaining 3.8e-08.
